解决方法:

尝试修改onPostExecute的代码：

@OverrIDeprotected voID onPostExecute(List<List<HashMap<String, String>>> result) {        ArrayList<LatLng> points = null;        //polylineoptions lineOptions = null;        //MarkerOptions markerOptions = new MarkerOptions();        points = new ArrayList<LatLng>();        // Traversing through all the routes        for(int i=0;i<result.size();i++){            //points = new ArrayList<LatLng>();            //lineOptions = new polylineoptions();                          // Fetching i-th route            List<HashMap<String, String>> path = result.get(i);            // Fetching all the points in i-th route            for(int j=0;j<path.size();j++){                HashMap<String,String> point = path.get(j);                                 double lat = Double.parseDouble(point.get("lat"));                double lng = Double.parseDouble(point.get("lng"));                LatLng position = new LatLng(lat, lng);                 points.add(position);                                   }            // Adding all the points in the route to lineOptions            //lineOptions.addAll(points);            //lineOptions.wIDth(4);            //lineOptions.color(color.BLUE);        }        // Drawing polyline in the Google Map for the i-th route        //map.addpolyline(lineOptions);         lineOptions.addAll(points);        lineOptions.wIDth(4);        lineOptions.color(color.BLUE);         line = map.addpolyline(lineOptions);    }           

我在for循环之前移动了列表点实例,在for循环之后移动了lineOptions.

希望这有帮助.
